Agelasphins, novel antitumor and immunostimulatory cerebrosides from the marine sponge Agelas mauritianus

Natori, Takenori,Morita, Masahiro,Akimoto, Kohji,Koezuka, Yasuhiko

, p. 2771 - 2784 (2007/10/02)

New glycosphingolipids, named agelasphins (1-8), have been isolated by antitumor and immunostimulatory bioassay-guided purification from an extract of a marine sponge, Agelas mauritianus. Strongly active agents in agelasphins had characteristic α-galactosylceramide structures, the isolation of which from natural products has not previously been reported. The absolute configurations of agelasphins were elucidated by the total synthesis.
